UPAYA OPTIMALISASI SISTEM FRESH WATER COOLER (FWC) TERHADAP KESTABILAN TEMPERATUR AIR PENDINGIN MESIN INDUK DI KAPAL MV.PUSRI INDONESIA 1

Abstract

This study aims to identify the cause of the increase in freshwater cooling temperature in the main engine on the MV ship. PUSRI INDONESIA 1. The coolant on the main engine is an important component in maintaining a stable and optimal operating temperature to support engine performance during the voyage. Based on the author's experience during sailing practice, it was found that there was a disturbance in the cooling system which was characterized by an increase in the temperature of the fresh water cooler from 70°C to 88°C, thus triggering an alarm sounding and slowing down the movement of the main engine. This research uses a qualitative method with a case study and problem solving approach, as well as data collection techniques through observation, interviews, and documentation. The results of this study will show that the cause of the increase in cooling temperature is the dirty sea chest filter and the clogging by sea garlic manure contained in the fresh water cooler tubes. Both conditions inhibit heat exchange efficiency and cause the cooling engine to not work optimally. Efforts to solve problems are carried out by carrying out routine maintenance according to the planned maintenance system, cleaning the sea water filter, and regular maintenance. This research improves technical understanding and serves as a reference for engine officers in maintaining the ship's cooling system.
